CRM1-mediated Recycling of Snurportin 1 to the Cytoplasm [PDF]
Importin β is a major mediator of import into the cell nucleus. Importin β binds cargo molecules either directly or via two types of adapter molecules, importin α, for import of proteins with a classical nuclear localization signal (NLS), or snurportin 1, for import of m3G-capped U snRNPs.

Rrp12 and the Exportin Crm1 Participate in Late Assembly Events in the Nucleolus during 40S Ribosomal Subunit Biogenesis [PDF]
This is an open-access article distributed under the terms of the Creative Commons Attribution License.During the biogenesis of small ribosomal subunits in eukaryotes, the pre-40S particles formed in the nucleolus are rapidly transported to the cytoplasm.

Recognition of nuclear export signals by CRM1 carrying the oncogenic E571K mutation
The E571K mutation of CRM1 is highly prevalent in some cancers, but its mechanism of tumorigenesis is unclear. Glu571 of CRM1 is located in its nuclear export signal (NES)-binding groove, suggesting that binding of select NESs may be altered.

Mutant NPM1 in Acute Myeloid Leukemia Initiation and Maintenance
NPM1 mutations drive acute myeloid leukemia by acting as neomorphic transcriptional regulators that cooperate with Menin–MLL and XPO1 to sustain HOX/MEIS1 expression and block differentiation. Targeting these mutant‐specific transcriptional dependencies provides a rational therapeutic strategy for NPM1‐mutated AML.

Cellular mRNAs are exported from the nucleus as fully spliced RNAs. Proofreading mechanisms eliminate unprocessed and irregular pre-mRNAs to control the quality of gene expression.

Role of SoxE transcription factors in development and disease
Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.

Putative Reaction Intermediates in Crm1-mediated Nuclear Protein Export [PDF]
We discovered several novel interactions between proteins involved in Crm1-mediated nuclear export of the nuclear export signal containing human immunodeficiency virus type 1 protein Rev. First, a Rev/Crm1/RanGTP complex (where Ran is Ras-related nuclear protein) reacts with some nucleoporins (Nup42 and Nup159) but not others (NSP1, Nup116, and Nup1 ...

Insights into the function of the CRM1 cofactor RanBP3 from the structure of its Ran-binding domain.
Proteins bearing a leucine-rich nuclear export signal (NES) are exported from the nucleus by the transport factor CRM1, which forms a cooperative ternary complex with the NES-bearing cargo and with the small GTPase Ran.

Karyopherin binding interactions and nuclear import mechanism of nuclear pore complex protein Tpr [PDF]
Background Tpr is a large protein with an extended coiled-coil domain that is localized within the nuclear basket of the nuclear pore complex. Previous studies 1 involving antibody microinjection into mammalian cells suggested a role for Tpr in nuclear ...
